Ubwa mbere, ikiguzi
Ibintu byiza: igiciro cya needle coke cyatumijwe mu Bushinwa cyazamuweho $100 kuri toni, kandi igiciro kizatangira gushyirwa mu bikorwa guhera muri Nyakanga, ibi bishobora gutuma igiciro cya needle coke nziza mu Bushinwa kizamuka hamwe nacyo. Igiciro cy'umusaruro wa electrode ya grafiti ifite ingufu nyinshi kiracyazamuka ku rwego rwo hejuru.
Ibintu bibi: igiciro cya coke ku isoko rya peteroli ya sulfur kiri hasi cyazamutse vuba cyane, isoko rya coke rya peteroli ya sulfur riri hasi vuba aha riragabanuka, igiciro kiragaruka buhoro buhoro ku buryo bufatika. Igabanuka ry'ibiciro byo gutwika peteroli ya sulfur riri hasi, hamwe no gutanga uruganda rutunganya peteroli ya sulfur riri hasi ntabwo bigenda neza, igiciro nacyo kirimo kugabanuka, bigatuma habaho igitekerezo cyo gutegereza no kureba ku isoko rya electrode ya grafiti.
Muri rusange: nubwo igiciro cya peteroli ya sulfur cyagabanutse, ariko ukurikije igihe nk'icyo umwaka ushize haracyari kwiyongeraho 68.12%; Igiciro cya needle coke yo mu rugo ku bikoresho fatizo bya graphite electrode kiri hejuru, kandi igiciro cya needle coke itumizwa mu mahanga cyariyongereye. Kuri ubu, igiciro cya needle coke yo mu rugo ku elektrode ya graphite kiri hagati ya yuan 9000-10000/toni. Igiciro cya needle coke itumizwa mu mahanga kiri hagati ya USD 1600-1800/toni, kandi igiciro cy'amakara gihindagurika mu ntera iri hejuru kandi nto. Ingano y'aside yahinduwe ikoreshwa mu bicuruzwa bya graphite ni yuan 5650/toni, kandi igiciro rusange cy'isoko rya electrode ya graphite kiracyari hejuru.

Icya kabiri, uruhande rw'ibicuruzwa
Isoko riherutse gutanga electrode ya grafiti riracyafite inkunga nziza, isesengura ryihariye ni iri rikurikira:
1. Isoko rya electrode ya grafiti muri rusange riracyari ku rwego rwo hasi kandi rukwiye, ibigo bya electrode ya grafiti byavuze ko ibigo bitagira ububiko burenze urugero bifite, isoko rya electrode ya grafiti muri rusange nta bubiko bifite kandi nta gitutu gifite.
2. Birumvikana ko muri iki gihe, bimwe mu bigo bitanga electrode ya grafiti bivuga ko bimwe mu bipimo bya electrode ya grafiti bitakiriho (cyane cyane ku ngufu nyinshi za 450mm), ibi bikaba bigaragaza ko gutanga imiterere y'ingufu nini cyane n'iciriritse bikiri bike kandi bito.
3. Muri Kamena, nk'uko bivugwa n'igice cy'ibigo bikomeye by'amashanyarazi bya grafiti mu Bushinwa bifite ubushobozi bwo gutanga ibikoresho bya needle coke ni bike, kandi kubera ko ibigo by'Abongereza bya needle coke ku ya 2 Gicurasi - kubungabunga, gutumiza needle coke hafi muri Nyakanga na Kanama kugira ngo bigere ku isoko, byatumye habura needle coke nyinshi zitumizwa mu Bushinwa, bityo igice cy'ibigo bikomeye by'amashanyarazi ya grafiti electrode binini, Kuri ubu, gutanga electrode ya grafiti electrode ifite ubushobozi bwo hejuru ku isoko biri ku rugero rwo hasi.
4. Bitewe n’izamuka ry’ibiciro bya koke y’inzoga ituruka mu Bushinwa, bimwe mu bigo bitanga electrode ya grafiti ntibifuza kugurisha, kandi isoko rusange rya electrode ya grafiti ni rito kandi rito.
Icya gatatu, icyifuzo kiri hasi
byiza
1. Vuba aha, hatangijwe inganda zikora ibikoresho by'amashanyarazi zo mu itanura rya grafiti mu gice cyayo giherereye inyuma ya electrode ya grafiti mu buryo buhamye. Igipimo mpuzandengo cy'imikorere y'inganda zikora ibikoresho by'amashanyarazi cyakomeje kuba hafi 70%, kandi ubukana bwa electrode ya grafiti bugomba kuba buhamye.
2. Vuba aha, isoko ry’ibicuruzwa byoherezwa mu mahanga bya electrode ya grafiti rihagaze neza. Dukurikije imibare y’amakuru ya gasutamo, muri Gicurasi 2021, ingano y’ibicuruzwa byoherezwa mu mahanga bya electrode ya grafiti yo mu Bushinwa yari toni 34.600, hamwe n’ubwiyongere bwa 5.36% buri kwezi n’ubwiyongere bwa 30.53% buri mwaka. Kuva muri Mutarama kugeza muri Gicurasi 2021, ibyoherezwa mu mahanga bya electrode ya grafiti mu Bushinwa byageze kuri toni 178.500, ubwiyongere bwa 25.07% ugereranyije n’igihe nk’icyo umwaka ushize. Kandi byumvikana ko hari ibigo bimwe na bimwe by’ibicuruzwa bya electrode ya grafiti byagaragaje ko isoko ryiza ryo kohereza mu mahanga kandi ko ibyoherezwa mu mahanga bihagaze neza.
3. Ingano y'itanura rya silicon metal riherutse ku isoko rya silicon metal yariyongereye buhoro buhoro, kugeza ku ya 17 Kamena, umubare w'itanura rya silicon metal ugereranije n'impera za Gicurasi wiyongereyeho 10, umubare w'itanura rya Baichuan statistical tanure ni 652, umubare w'itanura ni 246. Ubukene bwa electrode isanzwe ya grafiti ifite ingufu ni ukwiyongera guhamye, hagati n'aho ari guto.
bibi
1. Ibyuma by'umuriro w'amashanyarazi, bitewe n'igihe gito gishize mu nganda, kudashaka kugurisha ibiti, hamwe n'ibiciro by'ibiti biherutse bikomeje kugabanuka, kandi igabanuka ry'igiciro cy'ibiti riruta igabanuka ry'ibiciro by'ibyuma bishaje, inyungu z'ibyuma by'amashanyarazi biri mu gitutu, hamwe n'ibiciro bya peteroli ya sulfure biherutse kugabanuka, inganda z'ibyuma zikora amashanyarazi ku giciro cya electrode ya grafiti, tegereza urebe uko ibintu bimeze, hari icyifuzo cyo gushaka electrode ya grafiti.
2. Igiciro cy'ubwikorezi bw'amato yo kohereza hanze electrode ya grafiti kiracyari hejuru, ku rugero runaka, kibangamira kohereza hanze electrode ya grafiti.
Iteganyagihe ry’isoko nyuma y’isoko: nubwo isoko rya electrode ya grafiti riherutse rifite imiterere runaka yo gutegereza no kureba, ariko ikiguzi rusange cy’umusaruro w’isoko rya electrode ya grafiti kiracyari hejuru, urwego rwo hejuru rw’isoko rya electrode ya grafiti ruracyari ruto kandi rutoroshye, ibigo byiza bya electrode ya grafiti bitanga ikigo, byitezwe ko bizatuza imikorere y’ibiciro bya electrode ya grafiti muri rusange. Byongeye kandi, izamuka ry’igiciro cya needle coke itumizwa mu mahanga rishyigikira ikiguzi cya electrode ya grafiti. Bitewe n’imyumvire y’ibigo bikomeye bya electrode ya grafiti, haracyari igitekerezo cy’ubwiyongere ku ngufu nyinshi cyane n’uburyo electrode ya grafiti ikoreshwa cyane.
